Snowflakes are symmetrical

Every snowflake is a collection of snow crystals Snowflakes can consist of only 2 snow crystals or hundreds of snow crystals Snow crystals are frozen water molecules which bond to each other Snowflakes are formed when Snow Crystals grow into tiny, sometimes microscopic, "symmetrical" shapes. "Symmetrical" means: proportional, or having an equal number of parts. A perfectly formed 6-sided snowflake is called "symmetrical".

It's true, just like human fingerprints are each different, every snowflake is different
